[Norbe]

Just had my 2006 dodge 2500 4x4 Cummings diesel auto. In shop for front end damage. They replaced drivers exterior fender, bumper grill bumper mounts. While there had them install heater on Fass Pump system. Pick up truck, when started, anti
lock brake light on, brake light on. Driving it, has no speedometer, cruise, will not engage 4x4(electronic) has Jac-Brake, will not engage. looked at connectors lose wires, pull PCM and checked all connections for three hours before leaving body shop. Could not find anything. 232000 miles. These all worked when I pulled in.......

Northern Michigan. salt roads driving.

Help!!

Doesn't the 06 have the electronic fuse box(forgot the name) If it doesn't check the Power distribute center out (PDC). Hooking up the heater to the fass they mite of blew a fuse/relay or burned the whole thing up(electronic one). Are brakes/brake lights working.

May they forgot a ground wire, there are virtually dozens of it around the left fender and chassis.
also there is a connector behind the driver side wheel well that goes to rear of truck.
pull the wheel well, then you'll see all the cables and connectors, an easy task. No need to pull the wheel for it.

The jake , ABS , brake light all need the speedometer signal. The speedo sensor on the rear end is bad or disconnected. But could be the ECM as OZY says

Look to the rear abs sensor as it supplies speedo signal. A scan tool will give the location of abs sensor that's at fault. Then follow the wiring if the sensor checks out good. As has been suggested, look at the plugs behind the drivers inner fender.
